[Aortic dissection in childhood. Occurrence and diagnostic procedure].

Aortic dissections of the aorta thoracalis are rare in childhood, and mostly cause a life-threatening situation in which an immediate diagnosis is the key for survival. Main causes are an aortic vitium or a traumatic disruption. The conclusive diagnosis can only be obtained by a chest-X-ray, the two-dimensional echocardiography and the dynamic computed tomography scanning of the thorax. It must be taken into account, that patients with a polytrauma could possibly suffer from a traumatic aortic dissection, which sometimes can only be diagnosed at a later date.
